TikTok Senior Software Developer interview questions

This is my first time writing a review for an interview, and it's truly been such a frustrating and disappointing experience. I completed two rounds of coding interviews, addressing a total of three coding questions, and successfully passed all test cases for each one. I was very confident in my ability to pass the interview. However, I was surprised to receive a (no-reply) rejection email with no opportunity for further communication, not even feedback on my performance.

Made me speak in chinese which isnt my strong suit. So it was an immediate turn off for me. Probably be better for those more fluent in chinese. They had critical feedbacks of their intenal teams as well. Which probably points to a bad culture
